✦ Synopsis

The results of an earlier effort to provide a geometrical analysis of Hutchinsonian niche space are extended. The concept of diversity of a species in niche space is introduced and the maximization of this diversity provides a rationale for a within-niche fitness distribution which is Gaussian. Niche expansion is seen as a consequence of diffusion in niche space, and an evolutionary version of the Volterra competition equations is proposed as a way to relate niche geometry with population dynamics. Applications to topics in community evolution, species packing and the statistical fitting of species abundance data are mentioned.

A theory of protein spatial-structure evolution in terms of random walks in multidimensional conformational space is proposed. It is shown that the spatial divergence in pairs of homologous proteins depends only on their sequence similarity and is independent of the protein size. X-ray data are reas
